I am still struggling with this problem. There seems toi be only one board located just under the top panel at the front, close to the control knobs. This is in a plastic cover with many cable connectors attched. I have checke all of these connectors and seem ok. The fault is that it always fails during teh final spin cycle, although on a lighter load it did complete the program. Could it be some kind of torque ( current) sensing of teh motor or a tilt switch of some kind?

Thanks for any help

I am still struggling. Iidentified the Motor control board and have checked all cables and connectors between and on both boards and no joy. ( I only get to work on thsi at weekends) It still fails each time as the speed is ramping up during final spin ( lower speeds are ok) I checked out the cost of replacement boards and it is as much as a new machine (>400 UK Pounds).

So what I want to know is how can I get hold of the circuit schematics? I am good with electronics and may be able to repair these boards. I think it may be some over current trip circuit.

Thanks for any helpHi DrCool

Starting to see these fault codes pop up in these otherwise fine machines. The F/11 code
is just a generic code generated when there’s a communications error
between the two main control boards in the washer. These two boards are
the motor control unit(MCU) and the central control unit(CCU).
A common problem is the wiring harness jiggling loose; remove and
reseat it and that usually fixes it. If not, then you’re looking at
spending some money on control boards. Yes, I said boards, plural. The
really sucky part is that there’s no way to definitively and
conclusively prove which board, the MCU or the CCU, is at fault so,
unfortunately, that only leaves the parts changing monkey method: replace both boards,

But, on a brighter note, the electronics are covered under warranty
for 24 months. If your machine is older that this, then you’ll need to
shell out some shekels

the other board is located at the lower part of the unit. the motor control board. it is logical that with a big load( big vibration), less load ( less vibration), the wires could be loose more with a big load rather than with a small load.

the wires are just there and with vibrations, they become loose and disconnect and trigger the F21 error.

tnx again,

F06
Drive motor tachometer error
This error occurs when the main control unit fails to detect the motor speed from the tachometeric generator fitted to the motor either through an incorrect resistance or the tacho is not correctly fitted into place. The machine will try to detect the reading several times before aborting the program ans shutting down with this error being displayed.
When checking ensure that the drive belt and belt tension are okay as this can cause this error.

The F11 fault code indicates a serial communication error between the Machine Control board and the Motor Control board. This can be caused by several different problems.

A failed Machine Control board could be failing to provide the Motor Control board with proper voltage. If this is causing the F11 code, then the Machine Control board would need to be replaced.

The Machine Control board could also be failing to supply proper voltage to the door lock assembly. The Machine Control board would need to be replaced for this failure as well.

Voltage flows from the Machine Control board to the Door Lock Assembly. The Door Lock then energizes and closes the Door Lock MAIN Switch. Voltage flows out of the Door Lock Main Switch to the Motor Control board. So if you have power into the Door Lock Assembly but not out of the Main Door Lock Switch, it will give you an F11. If so, you will need to replace the Door Lock Assembly.

You could have a bad Motor Control board that is causing this failure. A bad wiring connection between the Motor Control board and the Machine Control board could also cause this fault code. A bad wiring connection between the Motor Control board and the drive motor is also a possible failure. A failed drive motor could also cause the F11.

With so many possible causes for this failure, I recommend calling a service technician to diagnose and repair the problem in your washer. If you are able to unplug the washer and check the wiring connections, you may be able to find a loose wire harness connection that is causing the problem. Much of the diagnosis for the potential problems noted above requires live voltage checks. I do not recommend conducting these types of checks yourself. Unless you want to take a chance and replace the Machine Control board and the Door Lock Assembly,

F11 Motor control unit internal failure MCU board failure or broken wire. Check that harness for loose connection to that white box on the left. That is the MCU. Get a tech manual for your machine HEREThis might just be a loose connection. The MCU pictured here is the white box on the left and aboveThe tech sheet is behind the kickplate also and it will give you the data you need for your codes.

F11 on a Whirlpool AWM9000:
Service manual says "Communication error between Control board and Motor control unit (MCU)".
-Check control board
-Check MCU
-Check wiring to MCU

Basically, there are two electronic boards in this machine- the one up the top that you use to operate the machine (control board), and a power board in the base of machine (MCU). F11 fault is indicated a communication error between these boards ie one of the boards may be faulty, or wiring connection between them may be faulty.
It is impossible to know which electronic board may be at fault, as there is no way of testing them. Would advise calling service technician, but would advise you use an actual Whirlpool technician rather than a local service man, as Whirlpool tech has access to technical info required to solve your problem.
Good luck !!(be wary- might pay to ask for an estimate of what repair might cost when booking service call, as some of the control boards can be expensive)

F-11 like a Kenmore means communication error between the motor control and the main control. Check connections, unplug and replug computer connections and see if problem persists. I've seen cases where either board or even both can be bad.

We've had this problem for about a yr when i finally firgured out how to correct it.
the problem is that the circuit board is attached to the washer, when it starts to shake it causes the connections to loosen and theats the fault code you get.
How I fixed this was to suspend the circuit from a bungie strap this will allow the washer to shake all it wants and the circuit board is stable, connections stay tight andwasher works fine, after 6 months not one error code at all
